Answer:
2 units
Step-by-step explanation:
because the only whole number factor pair to 10 is 2x5 and luckily, it turned out that 5-3=2, so there are no decimals or fractions. Yay!
To calculate time at t= 2 minutes. We substitute at t = 2.
h = 10.5 + 6.5 sin(850t)
h = 10.5 + 6.5 sin (850 * 2)
h = 10.5 - 6.4012 = 4.1 feet
Hence at time t = 2, height = 4.1 feet.
Answer: 68
Step-by-step explanation:
Formula for sample size when prior estimate of population proportion (p) is available: 
, where z*= critical-value.
E= Margin of error.
Let p be the population proportion of trees are infected with the citrus red mite.
As per given , we have

E= ± 0.08
The critical z-value corresponding to 90% confidence level = z*=1.645
Substitute all the values in the above formula , we get
Required sample size :

[Rounded to next integer.]
Thus, the minimum sample size should be taken =68
Answer:
The relationship is proportional. The constant of proportionality is 20. It represents how many meters the horse runs per second per second. Equation is d=20t
U should get the app "photomath" it will help u out alot!!!
